CLOSEOUT! Vintage Wood Synchroneous Tape Timer (THREE LEFT)

The ticker timer makes dots on a paper tape every fiftieth of a second. So if a piece of tape is pulled through the timer for a second there will be 50 dots on it.

Since the spaces between the dots take such a short time (1/50 s) the ticker timer is a very useful instrument for measuring short intervals of time.

A piece of tape is shown in the diagram. You can see that the faster the tape is pulled through the timer the furthest apart the dots get. If the tape is pulled through at a steady speed the dots remain the same distance apart.

We have to be very careful here; as there is 1/50 s between dots we must count the number of spaces and not the number of dots themselves.

To work out the velocity of the tape all we need to do is to measure the length of tape that goes through in the time given by the number of spaces.

INCLUDES everything needed to work. Plus, we have added a few rolls of additional tape.
